{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"SH31403P01A1000","brand":"Schneider Electric","brandSlug":"schneider","productSlug":"SH31403P01A1000","canonicalUrl":"https://aoctrl.com/schneider/SH31403P01A1000","factsUrl":"https://aoctrl.com/api/mcp/products/SH31403P01A1000","rawCanonicalId":null},"summary":{"shortDescription":"Schneider Electric SH3 series servo motor, SH31403P01A1000, 4.1 kW continuous power, 3000 rpm at 400 V three-phase, absolute single-turn SinCos Hiperface encoder, IP54/IP65, smooth shaft, without holding brake, 140 mm flange.","salesMarkdown":"## Speed-torque envelope across supply voltages The SH31403P01A1000 delivers 24.7 Nm nominal torque at 750 rpm on 115 V single-phase, and 12.9 Nm at 3000 rpm on 400 V three-phase — the torque curve shifts with the available supply. Continuous power reaches 4050 W at 400 V three-phase, dropping to 1940 W on 115 V single-phase. This is not a fixed-speed motor; the drive must be programmed for the actual line voltage to avoid overfluxing or under-torque. ## Encoder and feedback — absolute single-turn Hiperface Fitted with an absolute single-turn SinCos Hiperface encoder — no homing sequence needed on power-up for single-turn applications. The SinCos analog tracks give the drive fine position interpolation; the Hiperface protocol carries the absolute position over a serial link. Confirm the drive model supports Hiperface before wiring. ## Mounting dimensions and flange fit The motor uses an international standard flange with a 140 mm square pilot, 130 mm centring collar diameter, and 3.5 mm collar depth. Four M11 through-holes on a bolt circle matching the flange pattern — the 11 mm hole diameter accepts M10 bolts. Overall length is 327.5 mm with a 50 mm smooth shaft, 24 mm diameter. No keyway — the smooth shaft requires a clamping-type coupling or a keyless locking assembly. ## Environmental sealing and shaft loading IP54 as standard with the shaft bushing without seal ring; IP65 with the shaft seal ring fitted — both conforming to IEC 60034-5. The IP65 variant is washdown-capable but the smooth shaft seal is a wear item; budget periodic replacement in high-cycle applications. Maximum radial force is 2420 N at 1000 rpm, derating to 1670 N at 3000 rpm. Maximum axial force is 300 N — overhung loads from belt drives must be checked against these limits. ## Electrical constants for drive tuning Torque constant Kt is 1.58 Nm/A at 120 °C copper temperature; back-EMF constant Ke is 105 V/krpm at 20 °C. Stator inductance is 7.72 mH, stator resistance 0.4 Ω — these set the electrical time constant and influence the current-loop tuning gains in the servo drive. The motor has 5 poles (10-pole equivalent in some naming conventions), so the electrical frequency at 3000 rpm is 250 Hz.","metaTitle":"Schneider Electric SH31403P01A1000 Servo Motor, 4.1 kW","metaDescription":"Schneider Electric SH31403P01A1000 SH3 servo motor, 4.1 kW continuous power, 3000 rpm at 400 V three-phase, absolute single-turn Hiperface encoder, IP54/IP65","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Servo Motors with Brake"],"specifications":{"Phase":"Three phase","Length":"12.9 in (327.5 mm)","Shaft end":"Smooth shaft","Encoder type":"Absolute single turn SinCos Hiperface","Shaft length":"2.0 in (50 mm)","Holding brake":"Without","Nominal speed":"750 rpm 115 V single phase 1500 rpm 230 V single phase 3000 rpm 400 V three phase 3600 rpm 480 V three phase","Rotor inertia":"17.94 kg.cm²","Nominal torque":"218.6 lbf.in (24.7 N.m) 115 V single phase 187.6 lbf.in (21.2 N.m) 230 V single phase 114.2 lbf.in (12.9 N.m) 400 V three phase 80.5 lbf.in (9.1 N.m) 480 V three phase","Shaft diameter":"0.9 in (24 mm)","Torque constant":"1.58 N.m/A 248 °F (120 °C)","Type of cooling":"Natural convection","lifecycle_stage":"current","Continuous power":"4100 W","Mounting Support":"International standard flange","Sizing reference":"SH31403P","Back emf constant":"105 V/krpm 68 °F (20 °C)","Device short name":"SH3","Motor flange size":"5.5 in (140 mm)","Peak stall torque":"798.3 lbf.in (90.2 N.m) 115...480 V three phase","Stator inductance":"7.72 mH","Stator resistance":"0.4 Ohm","Maximum current Irms":"61 A","Nominal output power":"1940 W 115 V single phase 3330 W 230 V single phase 4050 W 400 V three phase 3430 W 480 V three phase","Centring collar depth":"0.1 in (3.5 mm)","Electrical Connection":"Straight connector","Electrical connection":"straight connector","Nbr. of units in pkg.":"1","Number of motor poles":"5","Maximum axial force Fa":"300 N","Temperature copper hot":"266 °F (130 °C)","Continuous stall torque":"246.05 lbf.in (27.8 N.m) 115...480 V three phase","IP degree of protection":"IP54 shaft bushing without shaft seal ring: conforming to IEC 60034-5 IP65 motor: conforming to IEC 60034-5 IP65 shaft bushing: conforming to IEC 60034-5","Maximum radial force Fr":"2420 N 1000 rpm 1920 N 2000 rpm 1670 N 3000 rpm","Mounting holes diameter":"0.4 in (11 mm)","Centring collar diameter":"5.1 in (130 mm)","Continuous stall current":"17.6 A","Maximum mechanical speed":"4000 rpm","Network number of phases":"3","Number of mounting holes":"4","Product or Component Type":"Servo motor","Speed feedback resolution":"128 periods","[Us] rated supply voltage":"115...480 V","Circle diameter of the mounting holes":"6.5 in (165 mm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5d126c013c74c77bf42e5653e3400b0d.pdf","sourceUrl":"https://www.se.com/nl/en/product/SH31403P01A1000/sh3-servomotor-140mm-3-stacks-smooth-shaft-sincos-singleturn-128-no-brake-straight-ip54-65/","alternativesUrl":"https://aoctrl.com/api/mcp/products/SH31403P01A1000/alternatives.json"},"ai":{"faq":[{"question":"What supply voltage and phase does SH31403P01A1000 require?","answer":"The motor is designed for three-phase supply, with nominal performance specified at 400 V three-phase (3000 rpm, 12.9 Nm) and 480 V three-phase (3600 rpm, 9.1 Nm).
